[AMDGPU] Restrict to VGPR only for mfma scale operands (llvm#158117)
Restrict to VGPR only (VRegSrc_32) for mfma scale operands to workaround a hardware design defect: For all Inline/SGPR constants, SP HW use bits [30:23] as the scale. TODO: We may still be able to allow Inline Constants/SGPR, with a proper shift, to obtain a potentially better performance. Fixes: SWDEV-548629
